  1. Hi Guys, I have a wonderful Arduino that does everything for me. It focuses, exposes, guides, does GOTO and a myriad of other things. It also give me the weather, well really only temperature and humidity. But from that it works out the dew point. Is there any point in waiting until the external temp drops below the dew point before turning on the dew heaters, or should I just leave them on all the time? This is what the output looks like now: "UTC: 2017/07/12 20:22:14 | 17 Deg C | 70 % humidity | Dew point = 11.5 Deg C " It keeps monitoring the conditions every few minutes and it can turn the heater on for me if I like, but should I bother? Maybe it's better on all the time. What do you think? Regards Steve
  2. Good afternoon, I know a few members are using USB temperature and humidity sensors to track the temperature and humidity (of course!) in their observatories. Which make/model do you recommend - are they reliable and where can one purchase them from? Is it possible to run more than one from the same machine? Thanks in advance :-) Mike
  3. Hi all! I just recently bought a laptop for using Maxim with my imaging (for now just shooting the pics, not guiding yet), and I immediately was confronted with the problem of humidity. On the first night out the pc was covered in moisture after an hour or two. I had to wipe the screen to be able to make out the Maxim windows... Does anybody have any tips on how to minimalise this, and avoid problems of shorting the motherboard, etc? Apart from keeping my fingers crossed, the only thing that comes to mind is a lapdome... Any thoughts appreciated!! Gerhard.
